Load Shifting Implementation in a Laundry Room under Demand Response Program
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Vale, ZitaIn order to overcome the consequences of high energy consumption, renewable energy resources advancement, smart grids development, and demand response programs effectiveness should be noticed and surveyed. Regarding the important role of buildings in energy consumption, another important factor is equipping the buildings and houses with automation. For this purpose, this paper presents an optimization algorithm...
Key performance indicators regarding user comfort for building energy consumpti...
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Abrishambaf, Omid; Vale, ZitaThis paper proposes an optimization approach to minimize the power consumption of an office building considering user comfort and key performance indicators. The present approach implements the power reduction by reducing power consumption of lights and air conditioners as reducible loads, and implements load shifting by considering dishwasher as shift able load. Two key performance indicators and several comfo...
Air conditioner consumption optimization in an office building considering user...
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Abrishambaf, Omid; Vale, ZitaThe rapid growth of energy consumption and its consequences in the last decades, made the world persuaded to energy optimization and energy management. Therefore, producers and prosumers should be equipped with the automation infrastructures to perform the management programs, such as demand response programs. Office buildings are considering as a proper case for implementing energy consumption minimization sin...
Energy Consumption Management in Buildings in the Context of Voluntary and Mand...
Khorram Ghahfarrokhi, Mahsa; Zheiry, Modar; Faria, Pedro; Vale, ZitaEnergy consumption is increasing around the world and has been made many consequences such as increasing greenhouse emissions, global warming, and climate changes. Demand response programs can be considered as techniques to manage and control electricity consumption based on user flexibility. There are several types of demand response programs that are categorized in price-based programs and incentive-based pro...
Sequential Tasks Shifting for Participation in Demand Response Programs
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Vale, Zita; Ramos, CarlosIn this paper, the proposed methodology minimizes the electricity cost of a laundry room by means of load shifting. The laundry room is equipped with washing machines, dryers, and irons. Additionally, the optimization model handles demand response signals, respecting user preferences while providing the required demand reduction. The sequence of devices operation is also modeled, ensuring correct operation cycl...
Lighting Consumption Optimization in a SCADA Model of Office Building Consideri...
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Vale, ZitaDue to the high penetration of the buildings in energy consumption, the use of optimization algorithms plays a key role. Therefore, all the producers and prosumers should be equipped with the automation infrastructures as well as intelligent decision algorithms, in order to perform the management programs, like demand response. This paper proposes a multi-period optimization algorithm implemented in a multi-age...
An Optimization Algorithm for Cost Minimization in Residential Buildings
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Abrishambaf, Omid; Vale, ZitaThe increment of the electricity consumption around the world has led many efforts on the network operators to reduce the consumption in the demand side and encourage to increase the use of renewable energies. Since the buildings have a significant part in energy consumption, and lighting systems have an important role in the energy consumption of the buildings, the optimization of the lighting system should be...
Air Conditioning Consumption Optimization Based on CO2 Concentration Level
Khorram Ghahfarrokhi, Mahsa; Zheiry, Modar; Faria, Pedro; Vale, ZitaNowadays, energy consumption increasing is a big concern for many countries around the world. Disadvantages and consequences of fossil fuels for the environment caused a lot of efforts to invest in renewable energy resources and programs to optimize energy consumption. All types of buildings are the major consumers of electric power. Therefore, buildings can be considered as good options for implementing optimi...
Optimizing Lighting in an Office for Demand Response Participation Considering ...
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Vale, ZitaThe world is moving toward demand response programs, energy optimization, and using renewable energy resources more than the past. Buildings are responsible for a significant part of energy consumption and they are considered as suitable cases for reducing energy usage. Therefore, energy management in buildings should be improved. This paper presents a multi-period optimization algorithm with the aim of reducin...
Demand Response Implementation in an Optimization Based SCADA Model Under Real-...
Khorram Ghahfarrokhi, Mahsa; Faria, Pedro; Abrishambaf, Omid; Vale, ZitaAdvancement of renewable energy resources, development of smart grids, and the effectiveness of demand response programs, can be considered as solutions to deal with the rising of energy consumption. However, there is no benefit if the consumers do not have enough automation infrastructure to use the facilities. Since the entire kinds of buildings have a massive portion in electricity usage, equipping them with...
